Authorities in Hallandale Beach, Florida, are intensifying their search for 25-year-old Jenny Saint Pierre, a pregnant woman who has been missing since August 5. Last seen at Gulfstream Park, her family is concerned as she has not been active on social media or contacted them, which is unusual for her. Saint Pierre, who has schizophrenia, is described as 5 feet 4 inches tall, weighing around 110 pounds, with black hair and brown eyes. Her sister revealed that she had an argument with her ex-boyfriend on the day she disappeared, which has raised concerns. Local police encourage anyone with information about her whereabouts to come forward to assist in the investigation. In a separate incident, Vero Beach High School increased security after a 16-year-old confessed to making threats on social media, though authorities determined it was not a credible threat.
